論述

CN803/809/810編控(kong)(kong)制(zhi)(zhi)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)源(yuan)電(dian)(dian)路是用以監測站電(dian)(dian)流(liu)電(dian)(dian)流(liu)或電(dian)(dian)池箱電(dian)(dian)流(liu)的微外理器重設控(kong)(kong)制(zhi)(zhi)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)源(yuan)電(dian)(dian)路。本編控(kong)(kong)制(zhi)(zhi)控(kong)(kong)制(zhi)(zhi)電(dian)(dian)源(yuan)電(dian)(dian)路不許要中心配(pei)件，故(gu)而(er)進步發展了(le)機(ji)制(zhi)(zhi)的靠受得(de)了(le)性，下滑了(le)機(ji)制(zhi)(zhi)的掙到。

本款型電(dian)(dian)(dian)(dian)(dian)路板在被監測系統(tong)的(de)主(zhu)機電(dian)(dian)(dian)(dian)(dian)源模(mo)塊電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值少于過后設立(li)的(de)重(zhong)置(zhi)閾值法(fa)(fa)法(fa)(fa)時，讀取要用(yong)的(de)重(zhong)置(zhi)旌(jing)旗燈號(hao)(hao)；當主(zhu)機電(dian)(dian)(dian)(dian)(dian)源模(mo)塊電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值下降到重(zhong)置(zhi)閾值法(fa)(fa)法(fa)(fa)綜上(shang)所述時，在很少140毫秒(miao)的(de)時期(qi)內初始化旌(jing)旗燈號(hao)(hao)還將保(bao)(bao)持著(zhu)用(yong)得(de)(de)著(zhu)。CN809/810提供給(gei)CMOS校(xiao)準鍵盤(pan)輸入(ru)，CN803供求(qiu)平衡漏極斷路導入(ru)。CN803和CN809的(de)回零錄入(ru)為低(di)有(you)所幫助，CN810的(de)歸位(wei)顯(xian)示為高有(you)效(xiao)果(guo)。在總體目標上(shang)后勤保(bao)(bao)障間歇候(hou)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)流適(shi)配(pei)器(qi)急劇(ju)下降沒反應歸位(wei)顯(xian)示。在全部室溫市場規模(mo)內，當電(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)流適(shi)配(pei)器(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)流低(di)至1.15V時仍能(neng)確(que)保(bao)(bao)靠(kao)得(de)(de)下搜索(suo)。

本類別(bie)電子器(qi)件(jian)包容3管腳的(de)SOT23封口。
